* [TSan] Let the users suppress use-after-free errors using the "race:" ↵Alexander Potapenko2013-08-073-10/+18
| | | | | | | | | | | | | | | | | suppressions. If there's a race between a memory access and a free() call in the client program, it can be reported as a use-after-free (if the access occurs after the free()) or an ordinary race (if free() occurs after the access). We've decided to use a single "race:" prefix for both cases instead of introducing a "use-after-free:" one, because in many cases this allows us to keep a single suppression for both the use-after-free and free-after-use. This may be misleading if the use-after-free occurs in a non-racy way (e.g. in a single-threaded program). But normally such bugs shall not be suppressed. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@187885 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "[sanitizer] Intercept sched_getaffinity."David Blaikie2013-08-072-2/+0
| | | | | | | | | | | | This reverts commit r187788. The test case is unreliable (as the test may be run in a situation in which it has no affinity with cpu0). This can be recommitted with a more reliable test - possibly using CPU_COUNT != 0 instead (I wasn't entirely sure that a process was guaranteed to have at least one affinity, though it seems reasonable, or I'd have made the change myself). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@187841 91177308-0d34-0410-b5e6-96231b3b80d8

* tsan: treat SIGSYS as synchronous signalDmitry Vyukov2013-07-181-1/+2
| | | | | | | | | | It is required for chromium sandboxing code. From the description it seems to be indeed synchronous -- called back on syscall with incorrect arguments, but seems to be unused in practice. So this should be fine. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@186579 91177308-0d34-0410-b5e6-96231b3b80d8
